LaunchPad is a low-cost, low-power-consumption microcontroller from Texas Instruments, the manufacturer of BeagleBone. The Value Line LaunchPad is available for $4.30 in a kit that comes with a second chip. The MSP430 chip also offers a power-saving mode that awakens almost instantly, which may be perfect for remote sensors. At a fraction of the price of Arduino, LaunchPad looks like a good alternative, at least for relatively simple projects. However, it packs 512 bytes of RAM compared with Arduino Uno's 2 kB, so Arduino might still win out for more complicated work.
